Fixation
Generally 10% neutral buffered formalin.
See also: General notes on fixation
Gross processing
- Perform consecutive slicing of the entire specimen.
- Look for signs of liposarcoma: Mainly by firm volumes.[1] Color varies from yellow to white (and firm) depending on the proportion of adipocytic, fibrous and/or myxoid content.[2] Areas of fat necrosis are common in larger lesions. Rarely, infiltrative growth is seen.[2]
- Submit slices from any suspicious parts, or at least one representative slice from the specimen.
Gross report
